Hi Kathleen, In this case, the generated identifiers are used for uniqueness so that each router will have a different System ID. The identifiers aren't used otherwise. The System IDs are flooded throughout the network as part of IS-IS. I don't see a privacy concern here - but agree that it is good to step back and double-check.
